Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Tracing the Evolution of SMBHs and Stellar Objects in Galaxy Mergers: A Multi-mass Direct N-body Model
星系合并 SMBH 恒星物体演化 多质量 直接N体模型
2023/11/13
By using direct N-body numerical simulations, we model the dynamical coevolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to investigate how diff...
Galaxy Zoo: Dust lane early-type galaxies are tracers of recent, gas-rich minor mergers
galaxies: evolution — galaxies: interactions — galaxies: active — galax-ies: elliptical and lenticular
2011/10/17
We present the second of two papers concerning the origin and evolution of local early-type galaxies exhibiting dust features. We use optical and radio data to examine the nature of AGN activity in th...
Relics as probes of galaxy cluster mergers
Cosmology: large-scale structure of Universe – Galaxies: Clusters: general, intracluster medium
2011/10/12
Galaxy clusters grow by mergers with other clusters and galaxy groups. These mergers create shocks within the intracluster medium (ICM). It is proposed that within the shocks particles can be accelera...
Long-term evolution of massive black hole binaries. IV. Mergers of galaxies with collisionally relaxed nuclei
large-scale structure of Universe – cosmology: theory – cosmology: observations – cosmological parameters
2011/10/12
We simulate mergers between galaxies containing collisionally-relaxed nuclei around massive black holes (MBHs). Our galaxies contain four mass groups, representative of old stellar populations; a prim...
